various distances apart, thereby adapting the drill for various uses.

A further object of the invention is to provide an attachment in theform of a'square shaft to be secured to the planter in prox- S imity tothe main shaft of the drill so that the attachment will not in. any wayinterfere with the operation of the main shaft.

With the foregoing and other objects in .view which will appear as thedescription bination and arrangement of parts and in the details ofconstruction hereinafter described and claimed, it being understood thatchanges in the preciseembodim'ent of 3 the invention herein disclosed,may be made within the scope of what is claimed, without departing fromthe spirit of the invention.

Referring to the drawings: v 0 Figure 1 is a plan view of a drillequipped with an attachment constructed in accordance with theinvention.

5 by the reference character 5 and includes side rails connected by thecross bar 6 which has its ends extended at right angles and bolted tothe side bars of the frame at 7. I

The frame is wheel supported-and'is pro vided with bearings 8 in whichthe axle 9 Figure 3 is a vertical sectional view' operates on' whichaxle the wheels 10 are mounted. The grain container of the-planterisindicate d by the reference character 11, a'ndis of the usual and wellknown constructi'on, the same being provided with the usual 55accumulatornot shown, which is actuated by theshaft 12 which has itsends mounted in bearings positioned in the end bars 13 of thetransversely disposed frame 14. This shaft 12 receives motion from theaxle ,9, throughthe medium of the chain 15 that 0perates over thesprocket 16 mounted on the axle 9, as'well as over the sprocket 17 mounted on theshaft 12. Y I 'A clutch member 18 is splined on the axle 9 andmoves to engage the clutchmember 19 .of the sprocket 16 so that thesprocket 17 may be thrown into and out'of operation at the will of theattendant. Sprockets 20 and 21 are also mounted on the shaft 12 and as 7shown are of various sizes so that by short ening the chain. 15, thespeed of operation may be increased. Set screws 22 are provided on thehub 23 and clutch member 19, so that the hub 23 and clutch member may be-ad-' 75 j'usted ontheir supports- 7 The clutch member 18 is operated bymeans of'the bell crank lever 24 and rod 25,'the rod 25 being'operatedbythe lever 26 l'ocated adjacent to'the drivers seat The referencecharacter 27 designates the delivery spout of the planter leading fromthe grain container, and throughwhich grain is delivered 'to the furrowformed by the blade 28.- e

Mounted'within the delivery spout 27 are s5 pivoted valves 28' and 29respectively, the valve 28 being mountedon the shaft 30, while the valve29 is mounted on the shaft 31. One end of the shaft 30 extends laterallyas at '32 at a point exteriorly of the delivery spout where it hasconnection with the link 33 that also connects'withfthe arm 34 formed atone end oft he shaft 31. An arm 35 also extends from the shaft-.131 andis disposed at right" angles to the arm' 34, the arm 35 being 'con- 9nected with the arm 36 which in turn has pivotal connection with the arm37 which ispivotally supported onthe frame of the machine.

5 As clearly shown by Figure 4 of'the draw-' ings the valves 28and 29are so positioned on their shafts that when one blade is moved to itsclosed position, the other blade swings to its open position to the endthat seeds dropped onto the upper valve 29, which occurs when the valve29 is in its closed position, will be dropped onto the valve 28, whichmoves to its closed position when the valve 29 moves to its openposition. The seed drops into the furrow formedby the blade 28, when thevalve 28 moves to its open osition.

Disposed above the arm 3 is a shaft 38 on which the trip 39 is secured,the trip 39 extending downwardly from the shaft 38 to be engaged by theupper end of the arm 37 so that movement of the trip 39 will operate tomove the arm 37 to indirectly operate the valves 28 and 29. I

A trip shown at 40 extends upwardly from the shaft 38, the trip 40 beingdisposed in the path of travel of the member 41 which is mounted on theshaft 12, and includes arms 42 that have curved extremities 43 adaptedto contact with the roller 43 of the trip 40 to move the shaft 38 andtrip 39.

A coiled spring 44 connects with the upper end'of the arm 37 and hasconnection with the side bar of the frame so that when the arm 37 andtrips 39 and 40 have been moved by the member 41, the spring will act toreturn the arm 37 and trips 39 and 40 to their normal positions.

' In the operation of the machine, it will be seen that as the shaft 12rotates and the curved ends of the arms 43 strike the trip 40, the shaft38 and trip 39 will be operated. As the trip 39 moves, the arm 37 willbe moved and the arm 36 will operate to swing the valve 29 to its closedposition which action moves the valve 28 to its open position droppingthe seeds resting on valve 28.

The coiled spring 44 will now act to return the valves to their initialpositions whereupon the accumulator will operate to drop seed onto thevalve 29, and the operation as described will be repeated, depositingseeds at predetermined intervals to insure an even planting.

While I have shown and described the invention as applied to a planter,it is to be understood that it is within the scope of the invention toemploy the device forming the subject matter of this invention, inconnection with listers.

I claim:

The combination with a planter having a discharge spout and having arotary shaft mounted thereabove, of a grain delivering device includingan upper swinging valve and a lower swinging valve mounted within thespout, arms connected with the swinging valves, a rod connected with thearms, a rod connected with one of the arms and extending forwardlytherefrom, a pivoted arm mounted on the frame and to which the lastmentioned rod is connected, a trip, mounted
